A 20 gauge is kind of small for geese, 3 inch magnums or not.
Son shoots a 870 20g and I'm guessing 3in mags will do the job .
Nice speck Hitman. How do you like that Xtreme? I was looking at shotguns last night and was torn between that one, the Benelli Super Vinci, and SBE 2. I really like the Kick-off recoil reducer and the fact that it is more rust resistant for Louisiana Marshes on the Xtreme, but that Super Vinci sure fit nice..... Even though that is one ugly SOB.
Watch that tone when speaking about the 1100's Emperor! That's probably my favorite skeet gun I have. When I point the barrel at it, the clays just break. If only mine shot 3" shells I wouldn't need another shotgun. That one would be in the blind with me every morning.
